A guy could probably load 90s backwards, at mag length, thereby:I’ve made some with 77s and TrailBoss for a suppressed bolt action 223. Definitely more energy in steel than any 22LR...lot more expensive in this age of scarce components, too.
All jokes aside, subsonic 223 is exceedingly hard to accomplish, won't cycle any semi-auto, and is almost, if not completely, pointless.
When I hear Subsonic I think bolt-action
A guy could probably load 90s backwards, at mag length, thereby:
—taking up quite a bit of the wasted volume;
—enabling stabilization of an extremely high SD bullet, as heavy-for-caliber as possible;
—slowwww down muzzle velocity;
—and increase impact violence by sending what amounts to a very small Keith nose down range.
I would imagine effective BC would still be decent, at SUBsonic speeds.
Whaddaya think avboiler?
THISStandard velocity .22 Long Rifle. You can even get a kit so that it will cycle in an ar15.

I have no advice other than finding the heaviest .223 bullet you can, using a pistol powder in combination with a case filler, and being super careful to not let a secondary explosion effect ruin your gun, or you.
Seriously, if you want a subsonic 22 caliber firearm, get a .22 Long Rifle and some standard velocity or sub sonic ammo. Aguila makes a super heavy sub sonic 22lr with a 60gr bullet that some people like.
